python xlrd,xlwt 讀寫excel檔案
python 讀excel檔案，需要xlrd庫。下載地址：https://pypi.python.org/pypi/xlrd
python 寫excel檔案，需要xlwt庫。下載地址：https://pypi.python.org/pypi/xlwt/1.1.2
下載後修改副檔名為rar, 解壓後安裝：
安裝成功後就可以引用了。如下程式碼：

結果如下：
##################單元格常用設定##############################
1、設定超連結
#設定超連結
font = xlwt.Font() # Create Font
font.colour_index = 4 # 藍色字型
font.underline=True
style = xlwt.XFStyle()
style.font = font
sheet.write(rowIndex,4,xlwt.Formula('HYPERLINK("https://www.baidu.com";"baidu")'),style)
2、設定單元格背景色
#設定單元格背景色
pattern = xlwt.Pattern()
pattern.pattern = xlwt.Pattern.SOLID_PATTERN
pattern.pattern_fore_colour = 5 #黃色
style = xlwt.XFStyle()
style.pattern = pattern
sheet.write(5, 5, 'Cell Contents', style)
''' 顏色值
0 = Black, 1 = White, 2 = Red, 3 = Green, 4 = Blue,
5 = Yellow, 6 = Magenta, 7 = Cyan, 16 = Maroon,
17 = Dark Green, 18 = Dark Blue, 19 = Dark Yellow ,
20 = Dark Magenta, 21 = Teal,
22 = Light Gray, 23 = Dark Gray
'''
3、設定粗字型
style = xlwt.easyxf('font: bold 1')
sheet.write(5, 5, 'Cell Contents', style)
4、設定字型顏色
style = xlwt.easyxf('font: bold 0, color red;')#紅色字型
sheet.write(5, 5, 'Cell Contents', style)
5、設定列寬頻
sheet.col(1).width = 3333 # 3333 = 1" (one inch)
6、設定日期格式
style = xlwt.XFStyle()
style.num_format_str = 'YYYY/MM/DD h:mm:ss'
sheet.write(5, 5, datetime.datetime.now(), style)
#Other options: D-MMM-YY, D-MMM, MMM-YY, h:mm, h:mm:ss, h:mm, h:mm:ss,
# M/D/YY h:mm, mm:ss, [h]:mm:ss, mm:ss.0
7、合併行和列
sheet.write_merge(0, 0, 0, 3, 'First Merge')
sheet.write_merge(2, 4, 0, 3, 'Second Merge')
8、給單元格增加邊框
borders = xlwt.Borders() # Create Borders
borders.left = xlwt.Borders.DASHED
# May be: NO_LINE, THIN, MEDIUM, DASHED, DOTTED, THICK, DOUBLE, HAIR, MEDIUM_DASHED, THIN_DASH_DOTTED, #MEDIUM_DASH_DOTTED, THIN_DASH_DOT_DOTTED, MEDIUM_DASH_DOT_DOTTED,
#SLANTED_MEDIUM_DASH_DOTTED, or 0x00 through 0x0D.
borders.right = xlwt.Borders.DASHED
borders.top = xlwt.Borders.DASHED
borders.bottom = xlwt.Borders.DASHED
borders.left_colour = 0x40
borders.right_colour = 0x40
borders.top_colour = 0x40
borders.bottom_colour = 0x40
style = xlwt.XFStyle() # Create Style
style.borders = borders # Add Borders to Style
9、設定單元格中內容中位置，居中，局左右等
alignment = xlwt.Alignment() # Create Alignment
# May be: HORZ_GENERAL, HORZ_LEFT, HORZ_CENTER, HORZ_RIGHT,
#HORZ_FILLED, HORZ_JUSTIFIED, HORZ_CENTER_ACROSS_SEL, HORZ_DISTRIBUTED
alignment.horz = xlwt.Alignment.HORZ_CENTER #水平居中
# May be: VERT_TOP, VERT_CENTER, VERT_BOTTOM, VERT_JUSTIFIED, VERT_DISTRIBUTED
alignment.vert = xlwt.Alignment.VERT_CENTER #垂直居中
style = xlwt.XFStyle() # Create Style
style.alignment = alignment # Add Alignment to Style
sheet.write(5, 5, 'Cell Contents', style)
